Invasion At Our Border

Do we have an invasion at our Southern border of the United States of America? Are we even a sovereign nation? Is it fair to the American people to allow all these illegal immigrants into our country.
Is it moral to allow just anyone to come into our country?
Who will pay for all these illegal immigrants coming into our nation?
These are questions we need to confront and people need to discuss throughout America.
Military age men are coming in to our nation on the Southern border.
They are using our resources that taxpayers are paying for. Some are raping and attacking civilians even police officers.
And there are known terrorists that are coming across our border. We indeed are being invaded by foreign nations.
And who is funding all of this and why?
